,Be it known that I, JAMES" S'TnoNe, acitizenof the United States, and resident of Hillburn, in the county ofRockland and .State of New York, have invented certain new and useful Improvements in Switch Rods for Slip Switches, of which the following-is a specification, j

.f. This invention-relates to improvements in switch rods for slip switches and the operating connections therefor.

' A limitedfreedorn', ofmovement is very desirable'between the switchpoints and, the switch rods which are operatively connected with the. operating mechanism, interlocking and signal indications, whereby movement of the switch iscontrolled, andthisinvention relates to improved means for interconnecting the switch points, particularly in double slip switches, to secure certainty of operation. ,to permit: the necessary adjust- IXlBIItS'tO bema de quickly and-securely, and

to prevent binding between the parts. a a

I The inventionfurther relates to improved means for attaching theswitch rods' to the vswitch points,'so ast o reinforce the points and insure proper throw against the; main or stock rails. I The invention lso relates to the 'constructlOILzOf the switch rods and the means for cOnneCtingthem to the switch rails; and for insulating the rods, and the. switch rails from eachother. In-the accompanying drawings, 9

--Fig. 1 1s a plan view, of a double slip switch embodying my invention; Fig. 2 is a side elevation ofthe same; Fig, 3 is a detail viewflof the connection betweenthe end bars andjthe swingdogs';

Fig, 4,.is an enlarged planrview ofthei connection between the switch rod and the end of switch point; and 1 j Fig. 5 is a detail sectional view of the 'insulation of the switch rods. 1 The switch "rails 1 may be of the usual construction,. and are movable toward and awaytfrom the main or stock rai-ls "2 to open or close the switch by switch rods 3. The four switch points illustrated-inthe drawings, are secured respectively to r the inter usual a manner.

O fshown, or other means to actuate the switch. I Y

The interlocking rod and the throwerod' are. each constructed in substantially, the same manner, and thedescriptlon of;one is JAMES STRONG, or HILLBURN, NEW YORK,ASSIG1\TOR TO RAMAro Aux CORPORA- applicable to the other." Each comprises 1 two end bars 5' and a center bar ,6' that is rigidly bars. r a I The center bar is in two parts spaced secured to a and connects the end apart asatE'TQsecure'd together by splice plate 8. An insulating member or washer 9 -is interposed between thesplice plates and the adjacent parts ofjth'ecent'er bar, andfthis insulation is ',-formed with an outwardly extending flange 10, whichfser ves asa protecting cap seating on the top o-fthesplice plate and prevents short circuiting through "the accidental dropping of a bolt of an conducting material across the short space'that separates; the'splice plat'e and the switch rod when the insulation is aipplied the" fv'lhe innerend '11. bf, "each end bar is page erably'forge'd and raised above the level of the switch rod, and projects'over the "center end is, threaded-and is connected with the switch point by a swing dog.;12 provided with a lip or flange '14 extending above the therewith. a 4 ,t

Inorder to, protect thev threads on the, end barfand provide a bearingfor the swing dog, a sleeve 16..is threaded thereon, said sleeve being integral with a flange 'orf nut 17,

bar and parallel-therewith. This projecting I a level of the threaded projection lljand ha'ving an eye] or K perforation 15 tov interlock ends.

certainty of operation is attained.

the walls of the eye 15 of the swing dog are beveled as t 20, and the perforation is preferably rounded as at 21, thus permittinga swiveling movement of the swing dog in the socket or groove provided by the bearing sleeve 16 and the jam nut 18.

The opposite end 'of the swing dog is connected directly to the switch points by a connection which will allow a swinging movement, such, for example, as a cone and socket joint 22. Consequently the swing dog swing-dog isfattached in advance of the switch rail point. It is Obvious that the clip may terminate with the switch rail, but

my preferred construction brings the thrust in a line that practically insures snug seating vof the ,switch point in itso-perative position, and also reinforces andstrengthens the switch point, thus providing an added factor of safety.

By means of my improved construction the'number of parts heretofore used in malting connections for double slip switches is decreased, lost motion is reduced, and greater At the same time .greatflexibility and freedom from binding in, case of creeping of one or more of the switch points isprovided, also the pivotal flexible bearings allow minimum resistance against throwing of the operating mechanism, The parts are readily assembled and adjusted, and an effective insulation is also obtained.

That I claim asmy invention is: 1. In a switch mechanism, the combination of a switch rail, and a switch rod for operating the switch rail, and a swing (log between the rail and rod, the rod being provided with a'fo 'ged end having an adjustable bearing surface thereon, and the swing dog engaging said bearing and havingalimited swinging movement thereon.

2. The combination of a switch rail, an operat ng rod therefor having a threaded projecting end, a sleeve nut on said rod, and.

a link provided with an eye interlocking with said sleeveand hav ng limited movementrelative thereto, said link being piv- 'otally connected to the switch rail;

, In a switch mechanism, the combination of a switch rail, a clip rigidly secured thereto and projecting beyondthe point of the switch rail, a swing dog pivoted to the clip beyond the switch point, and a switch rod connected to the swing dog, one of said parts having a bearing for the other part.

In a switch mechanism, the combination of a switch rail, a clip secured thereto and projecting beyond the point of the switch rail, a swing dog pivoted to the clip beyond the switch point, and a switch rod for actuating theswitch raih'said rod being provided with an integral projecting end engaging through an eye provided in the swing dog.

5. In aswitch mechanism, the combination of a switch rail, a switch rod for operating the switch rail, a swing dog between the rail and rod, said swing dog having one end movably secured to the switch rail and the other end adjustably secured to the, switch rod, and means mounted on the rod engaging the swing zdog to hold the, same against longitudinal lmovement but permitting swinging inovementrelative thereto.

6. In a switch mechanism, the combination of a switch rail, a switch rod for'oper ating the switch rail, a swing dog between the rail and rod, said rod being provided with a projecting end having an adjustable hearing sleeve thereon adapted to engage through an eye on theswing dog, and means for holding the swing dog against displacement on said bearing. 7 I

7. The combination of a plurality of switch points, a clip secured to each of the switch points projecting beyond the end thereof, a switch rod operating the switch points simultaneously, a swing dog between each switch point and the switch rod, one of said parts be ng provided with an adjustable bearing sleeve 7 adapted to engage through an eye on the other part, and means for insulating the switch points from each other.

8. In a'switch mechanism, a pluralityof,

switch points, a: switch'rod comprising a center bar formed in'two parts separated from each other. splice plates connecting the separated ends of the center bar, an insulating washer provided with an outwardly extending flange seating on top of the splice plate, and a swing dog connecting each of said points to the switch rod.

9. In aswitch mechanism, a plurality of switch points, a switch rod comprising a center bar formed in. two parts separated from each other, splice plates'connecting the separated ends of the center bar, and an insulating washer providedwith an outwardly eptending flange seating on top of the splice p, ate.

10. The combination of a plurality of switch points, a switch rod comprising an end bar having a threaded projection arranged out of line of the switch rod and,

a center bar formed in two parts separated from each other and connected splice plate, an insulating Washer between the splice plate and the" adjacent ends of the center bar formed'with a flangeextending 5 over the top of the splice plate, and a swing dog connecting each of the switch points to the switch rod, said connection comprising a healring adjustable on'siiid thi eeded Q swing dog Signed of -May, 1922.
